It's not just the hardness that counts
Monolithic full-contour restorations made by zirconium oxide material from Core3d Centres
Dental laboratories worldwide are following the trend rapidly, moving to a monolithic full contour restoration as an attractive alterative to layered porcelain restorations.
In a chewing simulation study by the University of Zurich, Full Morphology crowns, the new monolithic material from Core3d Centres, was convincing due to its low abrasive impact on ceramic materials and antagonists.
Starting April 2010, Core3d Centres - through its partners - introduced a translucent material to the dental market and offers an easy and reliable method to manufacture monolithic restorations from zirconium oxide. The Full Morphology crown incorporates the frame material zirconium oxide (zirconium dioxide), which is shaped the same as the natural tooth (full contour) in our CAD/CAM milling machines. Before Core3d Centres introduced this product onto the market, the University of Zurich was commissioned to carry out a study in which the abrasive behaviour of the Full Morphology restorations and antagonists should be examined.
The abrasion behaviour was compared against abrasion of natural tooth, a non-precious crown and a porcelain veneered zirconium oxide restoration. The test was carried out with 6 of each test specimens, on which a force of 50 Newton was exerted over 1.2 million cycles in an aqueous environment with temperature changes. The 1.2 million cycles stand for a period of wearing of 5 years. This simulation showed that the polished Full Morphology crown produced the lowest level of abrasion on the material and also caused the lowest abrasion on the antagonists. However, it also showed how important polishing is. The unpolished but glazed Full Morphology crown caused the highest level of abrasion on the antagonists. This is the result after the loss of the glaze layer under which the rough, unpolished zirconium oxide appears. In order to be able to apply a glaze layer to smooth polished zirconium oxide.
The polished Full Morphology crown is less abrasive in the 5-year simulation than a non-precious (CoCr) alloy or a veneering ceramic and even gentler than the natural tooth in this respect.

DTS 2010 - Review

Above - Cassandra, the Core3d Ambassador
The Dental Technology Show has been, and will continue to be, one of the most important UK shows for labs. As always there was a great variety of companies at the event, everyone was there from big worldwide leaders like 3M to local service providers such as us. The show is a great opportunity for visitors and companies to interact freely. Giving visitors the rare opportunity to discover, and investigate, new products, materials and technologies without the pressures of approaching a company directly. It is also a great opportunity for companies to shine and show the dental world what they have to offer, and we were no exception.
This year we wanted to create a buzz around the Core3d stand so we decided to hire a little helper. The lovely Cassandra became our Core3d ambassador for the full two days at the show. Armed with her Core3d cat-suit, and plenty of chocolate hand outs, she chatted to visitors and gave them a quick introduction to Core3d.
With Cassandra's help the stand became very popular very quickly and a crowd soon gathered to watch the 3Shape demonstrations take place. Kris, one of our most experience CAD/CAM technicians, demonstrated the true benefits of owning a D700 3Shape scanner. Kris showed how easy the software is to use and how quickly you can scan and create your design and even with difficult cases the D700 can provide you with detailed, accurate results. The 3Shape is of course just one product which we can offer labs and it is one of many Core3d products which we introduced visitors to at the show.
As well as the D700 demonstrations the other big hit was Compartis ISUS which we had on display on the screens on our stand. Compartis ISUS is a CAD/CAM designed, fully milled implant bar which can be placed on any implant platform. There was a great buzz about Compartis ISUS and it's easy to see why. CAD/CAM designed, made from cobalt-chromium or titanium they provide patients with a solution for life.
The show also gave us the opportunity to introduce our new pricelist which has expanded and changed thanks to our new international connections. These connections have given us the opportunity to introduce new products such as metal copings and introduce new lower prices for Zirconia. Find out more today
We were also able to introduce our new sales representative - Colin. Colin has over 15 years experience in sales and has a real passion for technology - so he fitted in perfectly.
And, last but certainly not least, we were also privileged to have the CTO of Brightsquid Dental link at our stand. Brightsquid is a revolutionary software which is quickly becoming industry standard for lab to dentist communication. Brightsquid is an innovative cloud base software which seamlessly integrates with most leading dental practice software and dental lab software to allow fully integrated communication between lab and dentist.

So after all those spent hours designing a stand, preparing the literature, packing up the technology and, of course, the travelling! After all that we had to ask ourselves "was it worth it?" And the answer? Definitely.
See you at the next DTS!
